Halfway Between 9 and 578

When you ask "What number is halfway between 9 and 578?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=578.

Halfway Between Line

To find the number halfway between 9 and 578, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 578 into our formula, we get:

(9 + 578)/2 = 293.5

Thus, the number halfway between 9 and 578 is 293.5.

To check that our answer is correct, we subtract 9 from 293.5 and subtract 293.5 from 578 and compare the two numbers:

293.5 - 9 = 284.5
578 - 293.5 = 284.5

As you can see, the halfway number is 284.5 higher than 9 and 284.5 lower than 578. Therefore, our halfway between answer of 293.5 above is correct.
